missing something stupid about sem-switch.c

missing something stupid about sem-switch.c

[Alan Lehotsky]

I don't seem to be able to cause sem-switch.c to be generated, and I haven't been able to figure
out why so far.

It there something "known" about this.  I've got maintainer mode enabled in the configure, I modified the
Makefile.in file to have a dependency between sem-switch.o and the stamp-cpu

If I manually run guile as per the directions in the docs file, I can run the (cgen-sem-switch.c) and it
spits out what looks like a good file to standard out.  But when I turn around and do the

		make arch
		make cpu
		make mloop

I end up without a sem-switch.c, AND I have a sem.c that won't compile because it wants to call SEM_BRANCH_FINI
with ONE argument, when the macro version we're expanding expects 3 arguments.

I know I'm doing something stupid - I just don't know what?

(I assume you meant sem-switch.c).

Can you post the relevant parts of your Makefile?  The shell scripts
that control generating the sim parts are not very intuitive and there
are a couple of subtleties.

I guess that you're trying to generate for a GNU simulators/gdb simulator.  
Lookin' in sim/common/genmloop.sh you that the script takes the following
argument:

   -switch file: specify file containing semantics implemented as a switch()

Example from the fr30-port Makefile:

stamp-mloop: $(srcdir)/../common/genmloop.sh mloop.in Makefile
        $(SHELL) $(srccom)/genmloop.sh \
                -mono -fast -pbb -switch sem-switch.c \
                -cpu fr30bf -infile $(srcdir)/mloop.in
